This work horse of a backpack with the expandable option made it possible to take a 14 day trip with all its storage, along with my carry-on. No worries about lost luggage. Also great for a student! The color, “Sterling Shimmer” on the website and shown in stock photos is not accurate, imo. It is more of a silver gray like in my pics. Backpack is PRISTINE inside and out. Comfortable straps Luggage sleeve 14.9x11x7 but expands in depth to 8.5 RFID pocket for passport Very lightweight! I love it so much, I’m selling this one at a very fair price to buy the same backpack in a different color!
